I left a comment on that thread linking to the original of the above image, which is from National Geographic Visions of Earth. The caption for this image was:

Photograph by Heidi and Hans-Jürgen KochApril 2008Germany—The see-through skin of an inch-long glass frog reveals her eggs. Native to Venezuela, the frogs lay eggs in bushes and trees overhanging streams. Tadpoles hatch, then tumble into the current to be swept away.

Wouldn’t that make pregnancy even more interesting than it already is!

I’d have a real problem getting used to people’s faces if we had transparent skin. I guess we’d all eventually get used to it, but in the meantime YUCK. It would be like living in one of those creepy old EC horror comic books.
